According to a follow up report from MMA Fighting.com, here is some of what Sonnen had to say about the choices he made, which eventually led to his retirement.

“People were saying, ‘why won’t he say he’s sorry?’ I’m not,” said Sonnen. “I’m not going to apologize because I’m not sorry. I’m a consenting adult. I knew exactly what I was doing. This was a premeditated decision.”

“Here’s the problem, is that it worked,” Sonnen furthered. “The problem is, it helps. There’s a term out there, performance enhancing drug. The reality is, it’s all medicine. All medicine is made to make you better. If it did the opposite, it would be malpractice. You’re not going to the doctor to say give me something to make me worse. i was taking things and they were making me feel a little better.”

The 37 year-old Sonnen retired from fighting having gone 28-14-1 since he turned pro in 1997. In his last outing, which took place at UFC 167 in November, 2013, the former middleweight contender was stopped by Rashad Evans in the first round.
